Method Detail

getStatementExecutionPlanText

public java.lang.String getStatementExecutionPlanText(int depth)

Return the statement execution plan as a String.

Specified by:

getStatementExecutionPlanText in interface ResultSetStatistics

Overrides:

getStatementExecutionPlanText in class RealDeleteResultSetStatistics

Parameters:

depth - Indentation level.

Returns:

String The statement execution plan as a String.

getScanStatisticsText

public java.lang.String getScanStatisticsText(java.lang.String tableName,
                                              int depth)

Return information on the scan nodes from the statement execution plan as a String.

Specified by:

getScanStatisticsText in interface ResultSetStatistics

Overrides:

getScanStatisticsText in class RealDeleteResultSetStatistics

Parameters:

depth - Indentation level.

tableName - if not NULL then print information for this table only

Returns:

String The information on the scan nodes from the statement execution plan as a String.

getNodeName

public java.lang.String getNodeName()

Format for display, a name for this node.

Overrides:

getNodeName in class RealDeleteResultSetStatistics

accept

public void accept(XPLAINVisitor visitor)

Description copied from interface: XPLAINable

This method gets called to let a visitor visit this XPLAINable object. The general contract is to implement pre-order, depth-first traversal to produce a predictable traversal behaviour.

Specified by:

accept in interface XPLAINable

Overrides:

accept in class RealDeleteResultSetStatistics

getRSXplainDetails

public java.lang.String getRSXplainDetails()

Specified by:

getRSXplainDetails in interface XPLAINable

getChildren

public java.util.Vector<ResultSetStatistics> getChildren()

Get the objects to be displayed when this tree object is expanded.

The objects returned can be of any type, including addtional Inspectables.

Returns:

java.util.Vector A vector of objects.

getEstimatedRowCount

public double getEstimatedRowCount()

Get the estimated row count for the number of rows returned by the associated query or statement.

Specified by:

getEstimatedRowCount in interface ResultSetStatistics

Returns:

The estimated number of rows returned by the associated query or statement.

getResultSetTimingsDescriptor

public java.lang.Object getResultSetTimingsDescriptor(java.lang.Object timingID)

Specified by:

getResultSetTimingsDescriptor in interface XPLAINable

getSortPropsDescriptor

public java.lang.Object getSortPropsDescriptor(java.lang.Object UUID)

Specified by:

getSortPropsDescriptor in interface XPLAINable

getScanPropsDescriptor

public java.lang.Object getScanPropsDescriptor(java.lang.Object UUID)

Specified by:

getScanPropsDescriptor in interface XPLAINable
